Patient presents with suspected Refeeding Syndrome, a potentially fatal complication of nutritional rehabilitation in malnourished individuals.  Presenting complaints include [Document specific patient complaints, e.g., fatigue, weakness, confusion, shortness of breath, peripheral edema].  Patient history significant for [Document underlying cause of malnutrition, e.g., anorexia nervosa, chronic alcoholism, prolonged starvation, chemotherapy, major surgery].  Physical examination reveals [Document relevant physical findings, e.g., tachycardia, hypotension, tachypnea, peripheral edema, altered mental status].  Laboratory findings demonstrate [Document electrolyte abnormalities including hypophosphatemia, hypokalemia, hypomagnesemia, and thiamine deficiency].  Differential diagnosis includes [List relevant differential diagnoses, e.g., heart failure, sepsis, pneumonia, hepatic encephalopathy].  Based on clinical presentation, laboratory findings, and patient history, the diagnosis of Refeeding Syndrome is established.  Treatment plan includes careful electrolyte monitoring, specifically phosphorus, potassium, and magnesium levels, along with thiamine supplementation.  Nutritional support will be initiated cautiously with a gradual increase in caloric intake, following established Refeeding Syndrome guidelines to prevent further complications. Patient education provided on the risks of rapid refeeding and the importance of adherence to the prescribed nutritional plan.  ICD-10 code E87.7 and related malnutrition codes will be applied.  Continued monitoring for cardiac arrhythmias, respiratory distress, and neurological changes is warranted.  Follow-up appointment scheduled to reassess electrolyte levels and adjust nutritional plan as needed.
